E-mail: kontscha@zoo.zoo.nhmus.hu Abstract - Three Uropodina mites are reported from Mauritius, one of them is a known species (Cyllibula magna ZlRNGIEBL-NlCOL et HIRSCHMANN, 1977), the other two, Oplitis mauritiensis sp. n. and Trichouropoda caudata sp. n. are described as new. With 11 figures. Key words - Uropodina, new species, Mauritius. INTRODUCTION In my previous paper (KONTSCHÁN 2004) I published Uropodina mites from Comoro Islands, while this paper contains data about another Afrotropical island, Mauritius. The Uropodina fauna of Mauritius - similar to most Afrotropical islands - is absolutely unknown (WISNIEWSKI 1993). The moss and soil samples from Mauritius were collected by Dr. TAMÁS PÓCS, the noted bryologist. Three Uropodina species were found in this material, one of them is already known, while the other two are new to science. The identified specimens are deposited in alcohol in the Collections of Soil Zoology of the Hungarian Natural History Museum.
